Gmod 13 Code Transfer

[G4m3rgods]

I saw on an older thread that some lua scripts can be transfered to gmod 12 to gmod 13. When i downloaded go fish on my gmod server it would all work except one file. I'm inferring that something with the code needs to be changed for it to work (like changing addons for a server to info.txt to addon.txt). If anyone knows how to fix this please tell me.

Here is the lua code from the whole file:

// FISHING FISH

AddCSLuaFile( "cl_init.lua" )
AddCSLuaFile( "shared.lua" )

include('shared.lua')

function ENT:SpawnFunction(ply, tr)
	return false
end

function ENT:Makeit()
	self.TheHook.HasCatch = nil

 	local NPC = ents.Create( Catchphrase[self.SelectedCatch][1] )
 	if ( !ValidEntity( NPC ) ) then return end 
	
 	NPC:SetPos( self.Entity:GetPos() + Vector(0,0,32)) 
 	
 	if NPC:IsNPC() then
		local SpawnFlags = SF_NPC_FADE_CORPSE | SF_NPC_ALWAYSTHINK | SF_NPC_NO_WEAPON_DROP
		NPC:SetKeyValue( "spawnflags", SpawnFlags )
		
		if NPC:GetClass() == "npc_citizen" then
			NPC:SetKeyValue( "citizentype", math.random(1,3) )
		end
		if NPC:GetClass() == "npc_seagull" or NPC:GetClass() == "npc_pigeon" or NPC:GetClass() == "npc_crow" then
			NPC:SetKeyValue( "target", "airtrack1" )
		end
		if NPC:GetClass() == "npc_combinedropship" or NPC:GetClass() == "npc_combinegunship" or NPC:GetClass() == "npc_helicopter" then
			NPC:SetKeyValue( "target", "airpath1" )
		end
		
			
		if ( Catchphrase[self.SelectedCatch][3] != nil ) then
			NPC:SetKeyValue( "additionalequipment", Catchphrase[self.SelectedCatch][3][math.random(1,table.getn(Catchphrase[self.SelectedCatch][3]))] )
		end
		
		NPC:SetName("Enemy")
		NPC:SetColor(255,150,150,255)

		if math.random(0,100) <= 30 then
			NPC:SetName("Friendly")
			NPC:SetColor(150,150,255,255)	

		end
		
		NPC:SetPos( self.Entity:GetPos() + Vector(0,0,256))
		
		for k,v in pairs(ents.FindByClass("npc_*")) do
			if v:GetName() == "Friendly" and v:IsValid() then
				v:AddRelationship("Player D_LI 99")
				v:AddRelationship("Enemy D_HT 99")
				v:AddRelationship("Friendly D_LI 99")
			elseif v:GetName() == "Enemy" and v:IsValid() then
			
				v:AddRelationship("Player D_HT 99")
				v:AddRelationship("Enemy D_LI 99")
				v:AddRelationship("Friendly D_HT 99")
			end
			if v:GetClass() == "npc_headcrab_black" and v:GetName() != "Friendly" and v:GetName() != "Enemy" then
				v:SetName("Enemy")
				v:AddRelationship("Player D_HT 99")
				v:AddRelationship("Enemy D_LI 99")
				v:AddRelationship("Friendly D_HT 99")
			end
		end
	
	else
		NPC:SetModel( Catchphrase[self.SelectedCatch][2] )
		
	end
	
 	NPC:Spawn() 
 	NPC:Activate()
	
	
 	if NPC:GetClass() == "npc_combinegunship" then
		NPC:SetModel("models/gunship.mdl")
	end
	if NPC:GetModel() != tostring( Catchphrase[self.SelectedCatch][2] ) then
		ErrorNoHalt( "ERROR: ".. tostring( NPC:GetModel() ) .." was supposed to be ".. tostring( Catchphrase[self.SelectedCatch][2] ) .."!\n" )
	end

	NPC.fishowner = self.fishowner
	self.fishowner:AddScore( 1 )
	
	local phys = NPC:GetPhysicsObject()
	if phys and phys:IsValid() then
	NPC:SetNetworkedInt("Weight", phys:GetMass())
	end
	
	self.fishowner:SetNetworkedInt("catches", self.fishowner:GetNetworkedInt("catches") + 1)
	ply = self.fishowner
	totalchange(ply)
	addcash(ply, 10)
	SPropProtection.PlayerMakePropOwner(ply, NPC)
	self:Remove()

end

function ENT:Use(activator, ply)
	self:Makeit()
end

function ENT:Think()
	self.Entity:NextThink(CurTime() + 10) -- Think only once a second instead of once per tick.
	if self.Entity:WaterLevel() >= 3 and self.pron != nil then
		self.TheHook.HasCatch = nil
		self:Remove()
	end
	self.pron = true
	return true
end	

function ENT:OnRemove()
end

function ENT:Initialize()
	self.SelectedCatch = math.random( 1, table.getn(Catchphrase))
	
	self.Entity:SetModel( Catchphrase[self.SelectedCatch][2] )
	
	self.Entity:PhysicsInit(SOLID_VPHYSICS)
	self.Entity:SetMoveType(MOVETYPE_VPHYSICS)
	self.Entity:SetSolid(SOLID_VPHYSICS)
	
end

function ENT:StartTouch( ent )
	if ent:IsPlayer()  then
		self:Makeit()
	end
end

function ENT:Touch( ent )

end

ValidEntity() was removed, use IsValid() instead under ENT:Makeit().

Also, it would be a lot easier to help if you post errors from console.

Tried what you said and it didn't work. Also heres what the console tells me before and after the change

We don't have bitwise operators anymore, so replace:

local SpawnFlags = SF_NPC_FADE_CORPSE | SF_NPC_ALWAYSTHINK | SF_NPC_NO_WEAPON_DROP

with

local SpawnFlags = bit.bor( SF_NPC_FADE_CORPSE, SF_NPC_ALWAYSTHINK, SF_NPC_NO_WEAPON_DROP )

Got rid of the unkown gamemode file for lua but now it says couldnt find weapons even though they are in the folder. Do i need to change the lua code for them to?
